[PROBLEM] Radio Stations do not play - Error = Could not resolve host (all stations do this)

[rongon]

Hi, 

Running Moode 8.3.9 on a RPi 3B+ 1GB. 
When I attempt to play a radio station I get an error "Failed to decode <URL>. CURL failed: Could not resolve host <curl>"
No audio plays. 

I'm connected through wifi to my home network, using a static IP address for the RPi. 

Music files connected through USB thumb drives to USB ports on the RPi play fine. It's just radio stations that won't play. 
The behavior is the same connecting to Moode from a Windows PC or Android phone. 

I restarted the RPi and behavior is unchanged. 

Connected DAC is a Topping D10 (USB). 

I'm happy to post any logs, screenshots, anything that might help understand what's happening, but I'm a networking a Linux noob. I'm likely to not understand some things. I apologize in advance for that. 

Any guidance would be much appreciated. Thank you.
